摘要:

本文基于Sehnorr不可抵赖签名算法提出了一个可追踪匿名的脱线式数字现金协议。它使用智能卡作为分布匿名代理,实现了数字现金的动态匿名和兑零的功能;证明数字 现金是安全的且满足可追究匿名性;协议的效率比基于盲签名和匿名代理服务器的协议高,可以应用于移动环境下的匿名支付。

Abstract:

An off-line anonymous digital-cash payment protocol is presented in this paper. It uses the smart card as a distributed anonymous provider agent based on the Schnorr signature scheme. It provides dynamic accountable anonymity and changing for digital cash. Digital cash is proved secure, and accountabl e anonymity is guaranteed. The protocol is proved efficient in mobile environments.
